We have a Tru64 5.1B (latest patchkit) NFS file server which causes
problems for the NFS clients (Linux PCs). The problem crops up when
we change the IP-address of the primary DNS server in /etc/resolv.conf
(because we have migrated our DNS service to another server).
Very strangely, as soon as we turn off our old DNS server (which is
no longer listed in Tru64's /etc/resolv.conf), a lot of NFS clients start
complaining that the "lockd" daemon on the Tru64 server is no longer
responding, and NFS comes to a grinding halt :-( As soon as we restart
the old DNS server, the problem goes away...
Question: Apparently the running daemons, such as rpc.lockd, do
not seem to dynamically register changes in DNS service in
/etc/resolv.conf. Is this a bug in some DNS resolver library ?
Is there a workaround (short of rebooting the Tru64 server) ?
Thanks,
Ole
